WIRE-COILING DEVICE.

SPECIFICATION forming part of Letters Patent No. 689,575, dated December24, 1901.

Application filed August 12 1901. Serial No. 71,716. (No model.)

To all whom it may concern.-

Be it known that I, MERTON CHURCH, a citi zen of the United States,residing at Detroit, county of Wayne, State ofMichigan, have invented acertain new and useful Improvement in Wire-Coiling Devices; and Ideclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention has for its object a wire-coiling device embodied in thefollowing specificationand illustrated in the accompanying drawings,in'whieh Figure 1 is a view in side elevation, illustrating myinvention. Fig. 2 is a plan view. Fig. 3 is a detail view of thecrank-shaft and bar actuated thereby. Fig. 4 is a view in verticalsection through one of the tensionwheels, showing the wire passedthereabout.

The aim of my invention more particularly is to provide a wire-coilingdevice for coiling fence-wire to give to the fence-wire a desired degreeof elasticity. I carry out my object as follows:

In the drawings any suitable supporting bed or frame is indicatedat a,upon which is journaled a reel, (indicated at 12,) upon which a supplyof wire c is wound. From the reel each wire passes over a tension-wheeld. It

will be understood that there are to be as many of these tension-wheelsas there are wires to be coiledl, I have shown three of thesetension-wheels in Fig. 2 of the drawings, but donot limit myself to anyparticular nu mber. I prefer that the wire a shall pass around thetension-wheel d, a smaller grooved guideroller e serving to hold thewire down upon the wheel (1/ The wheels 01 and the guideroller e aredesigned more particularly to give a desired tension upon the wire.

The coiling device more particularly consists of a crank-shaft f,provided with a crank arm g, journaled in any suitable manner upon thesupport at, the crank-shaft being driven also in any suitable manner.Thus, for example, the crank-shaftf may be provided with a pinion h,meshing with the pinion '5 upon a shaftj. The shaft is of the wheels (1is shown provided with a sprocket-gear Z, connected with asprocket-wheel m upon the shaft j by a sprocket-chain n, so that theshafts j it would be synchronously driven. I prefer to duplicate thecrank-shafts f on each side of the machine with the crank-arm g and thedriving-pinions h and t, the two crankshafts g g being connected by acoiling-barp, the wires 0 passing through said bar p. On either side themovable bar p are stationary bars q a", through which the wires 0 arealso passed, the coiled wires passing from the bar 4' either to a reels,as shown in thedrawings, or they might pass directly to a fence-weavingmachine. (Not shown.) The reel 3 may be driven in any suitable manner,as by a belt t upon a pulley u, geared with the shaft of the reel 8. Thetension exerted upon the wire to coil it upon the reel .9 or to carrythe wire to the weaving-m achine draws the wire through the coilingdevice.

It will be apparent that the bar 10 has a movement corresponding to themovement of the crank-arm g, the bar thus having a reciprocatory andoscillatory movement to coil the wire. It will be obvious that themovement of the bar 1) by the crank -ar1n constantly changes the pointof deflection of the wire, carrying the wire not only forward andbackward, but also giving to it at the same time an upward and adownward movement.

What I claim as my invention is-- 1. In wire-coiling mechanism, thecombination of a stationary device through which the wire is movable,and a bar having a longitudinally reciprocatory and oscillatorymovement, to deflect t l e wire in. a constantlychanging direction,whereby the wire is given acoiled or spiral appearance. I

2. "In wire-coiling mechanism, the combination with a stationary devicethrough which the wire is movable, of a bar having alongitudinally-reciprocatory movement engaging the wire to deflect thewire in a constantlychanging direction, whereby the wire is given acoiled or spiral appearance, crank-arms engaged with opposite ends of'the movable bar, and means to actuate the crank-arms. V

3. In wire-coiling mechanism, the combination of a stationary devicethrough which the wire is movable, of a movable bar to engage the wire,crank-arms engaged with both ends of the bar, a tension device, andmeans to synchronously actuate the tension device and the crank-arms.

4. In wire-coiling mechanism, the combination of two stationary devicesthrough which the wire is movable, of a movable bar to en- IO gage thewire intermediate the stationary de-
